STROFPING-MACHINE.

specification of Letters Patent.

Patented Nov. 5, 1907.

Application filed January 28, 1907. Serial No. 354.470.

To all whom "it may concern:

Be it known that I, Anons'r W. Pn'rnnsox, a citizen of the UnitedStates, residing at Highwood, in the county of Lake and State ofIllinois, have invented certain new and useful Improvements in aStropping-Machine, of which the following is a specification.

This invention relates to improvements in a stropping machine or adevice to be used for stropping blades of various kinds, such as razors,the blades of scissors and knives, and it consists in certainpeculiarities of the construction, novel arrangement, and

. operation of the various parts thereof, as will be hereinafter morefully set forth and specifically claimed.

The principal object of the invention is to provide a stropping machine,which shall be simple and inexpensive in construction, strong, durableand efficient in operation.

Another object is to provide detachable means for holding and adjustingthe blades of scissors so that they may be stropped by the device, andalso for holding knives of various constructions for the operation ofstropping the same.

Other objects and advantages of the invention will be disclosed in thesubjoined description and explanation.

ln order to enable others skilled in the art to which my inventionpertains, to make and use the same,

will now proceed to describe it, referring to the accompanying drawing,in which- I Figure 1 is a top plan view of a stropping machine embodyingmy invention, showing the attachment for holding the blade of a pair ofscissors in position thereon. Fig. 2 is a plan view of the machine withthe upper frame plate thereof removed, and showing the blade of a pairof scissors held by the attachment therefor and said attachment locatedin position on ,the rocking blade retainer. Fig. 3 is a horizontalsectional view taken about midway between the frame plates of themachine. Fig. 4 is a view in side elevation of the stropping machine,showing the attachment for the scissors in position in the retainer, andillustrating the opposite side of said attachment from that shown inFig. 5. Fig. 5 is a detached view of the scissors holding attachment,showing one side thereof in elevation; and Figs. 6 and 7 are detailviews of attachments for holding knife blades of differentconstructions.

Like numerals of reference, refer to corresponding parts throughout thedifferent views of the drawing.

The reference numerals 10 and 11 designate the upper and lower plates,respectively, of theframe of the machine, and are preferably made alikeand rectangular in shape and of skeleton form, as shown in Figs. 1 to 3,inclusive, of the drawing. Each of the frame plates 10 and 11 has at itsrear end apertured lugs 12 through which screws may be passed forsecuring the frame to the wall of a room, or other suitable support. Theplates 10 and 11 are spaced apart, as shown in Fig.

j 4, and are secured together at their front ends by means I, ofbrace-bars 13 and near their rear ends by a bracej rod 14, and aboutmidway between their ends by j means of rods 15, on each of which rods,with the exception of the rod 14, is mounted an anti-friction roller ior a sleeve 16, which are interposed between the plates i 10 and 11. Asshown, and as will be understood by j reference to Figs. 1 to 3,inclusive of the drawing, each ofthe plates 10 and 11 is formed in itsfront portion i with an open space 17, and that the rear edge of said iopen spaces is provided with a rearwardly extending j slot 18 enlargedat its front end for the operation of the blade retainer, and said slotsare also for the reception and operation of projections on the upper andlower ends of the blade retainer, as will be presently explained.Pivotally mounted on the rod 14 near each of its ends, and near theinner surface of each of the frame plates 10 and 11, is a rocking member19, each of which is substantially triangular in form and are unitedtogether at or near their outer angles by means of rods 20, on each ofwhich is mounted between the rocking members 19 an anti-friction rolleror sleeve 21. The rocking members 19 are also connected together at ornear their front angles by means of a rod 22, on which is pivotallysecured the blade retainer 23, which -is preferably formed of a singlesheet of metal bent or folded around the rod 22 and back upon itself,forming two plies 2 1 and 25 having at their front or free ends spacedapart jaws 26, which plies and jaws may be suitably adjusted so as tohold the blade or blade carrying attachment between said jaws by meansof a bolt 27 and a nut 28, which bolt passes through the said plies. Theblade retainer 23 may have located between its plies 24 and 25 avertically extending rod, the ends or projections 29 of which willextend through the contracted or rear portions of the slots 18 in theframe plates.

By reference to Figs. 1 to 3, inclusive, it will be seen that a leatherstrop 30, which may be of a width about is passed around the rollers orsleeves 21 on the rods 20 which the rocking members 19 carry, andiisthen extended between the sleeves 16 on the rods 15, which l i l equalto the space between the frame plates 10 and 11.

are spaced apart at a sufficient distance, so that the outer surfaces ofthe sides of the strop 30 will contact therewith, while the innersurfaces of its sides will contact with the rollers or sleeves 21 whilethe front portions of the strop are extended between the outer rollers16 on the rods 13 on the front portion of the frame. When the parts arethus assembled, it is apparent that V the frame may be secured to thewall of a room or other support, and that the blade of a razor may belocated vertically between the jaws 26 of the retainer 23, when bydrawing on first one end and then the other of the strep 30, the members19 will be caused to rock on their pivot 14, which operation will causethe retainer 23 to rock on its pivots or projections 29, so that firstone side of the blade will be presented against one side of the stropand then the other side of the blade against the other side, so that inthe reciprocation of the strop the blade may be sharpened.

As one of the objects of -my invention is to provide means forsharpening or stropping the blades of scissors, and as said bladesrequire stropping on one side only, I have provided an attachment, whichforms a part of the invention, for holding the blade of a pair ofscissors, which attachment consists of a plate or piece 31 having itsrear portion formed with an enlargement 32 to fit between the jaws 26 ofthe retainer 23, and said plate, as well as said enlargement 32 thereon,may be of any suitable length, but preferably somewhat shorter' than thedistance between the frame plates. The plate 31 is provided at its upperand lower ends with apertured lugs 33, which extend laterally from oneside of the plate, and have located in their apertures a rod 34 on whichis mounted an anti-friction roller or sleeve 35 against which one sideof the strop 30 may contact. In front of the lugs 33, the plate 31 isprovided with an angularly deflected portion 36, which is provided nearits ends'with horizontal slots 87, through which are passed aperturedlugs 38, produced on an adjustable jaw 39, which is bent to liealongside of the portion 36 so as to clamp the scissors blade 40 betweenit and said portion, which may be done by means of set-screws 41 locatedin the lugs 38 of the adjustable jaw, It will be observed by referenceto Fig. 5 that the lugs 38 are extended towards each other so that thescrews 41, when tightened, will rest against the surface of the angularportion 36, and that the slots will permit said lugs to be moved so asto adjust the jaw 39 to blades of different widths and taper.

In Fig. 6 I have shown an attachment which is adapted to be used forholding a butcher or table knife,

- which consists of two plates 42 and 43 secured together i l l bysolder or rivets so as to form at its rear portion an enlargement 44 tofit btween the jaws 26 of the retainer, and at its front edge withspaced apart jaws 45 between which the thickened portion of the knife orblade may be placed, so that its cutting edge may be presented to thesides of the strop.

In Fig. 7 is shown still another attachment for holding knives ofdifferent constructions, which consists of plates or members 46 and 47secured together to form an enlargement 44 to fit between the jaws 26 ofthe retainer 23, and its front edge spaced apart to receive thin blades.7

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters-Patent,

In a stropping machine, the combination with the spaced apart frameplates each having at about its middle a rearwardly extending slot andone of said plates having an opening in its front portion, of tie-rodsuniting said plates, antifrietion rollers located between the frameplates, a pair of rocking members pivotally mounted be-. tween the frameplates, anti-friction rollers journaled on said members between the sameand in a line with its pivot, a retainer pivotally connected at its rearportion to the front portion of the rocking; members and havingprojections at its ends to loosely engage the slots in the frame platesand provided at its front edge with adjustable jaws, a blade holdingattachment consisting of an angular plate having near its rear edge anenlargement to fit between said adjustable jaws and provided at itsupper and lower ends with apertured lugs, an anti-friction rollerjournaled on said lugs, a'jaw adjustably held on the front portion ofthe angular plate, and a strop extended around the antifriction rollerson the rocking members and be tween the rollers of the frame plates,substantially as described.
